5  ✕ 12 = 60

60 ✕ 2 = 120

Then B

8 ✕ 12 = 96

Then the triangles

3 ✕ 5 ÷ 2 = 12 / 2

But now think,because there are 2 triangles, so we have to times it by 2 later so we can just leave it like this.

120 + 96 + 12 = 228

x and y are not in a proportional relationship

Step-by-step explanation:

The temperature is 60 F at midnight, and decreases 2 F every 1/2 hour, x represents hours, y represents temperature.

Plot (0, 60) , (0.5, 58) , and (1, 56)

1 /7 ⋅  2 /2  +  9 /14

Write each expression with a common denominator of  14 , by multiplying each by an appropriate factor of  1 .

2 /14  +  9 /14

Combine the numerators over the common denominator.

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.


*Calculate Slope first

*Calculate y-intercept second

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)


Help quickly!!! I will give brainylist or whatever

Answers

Can you add an image please?

1. To find slope use the slope equation which would be (3 - -1)/ (5-3). The slope is m = 4\2 which is m = 2

2. Plug in one of the points to find the y-intercept. Using the point (5,3) , you would plug this point into the slope intercept equation, along with the slope which was found. 3= (2 x 5) +b. Solving this equation b=-7

3. The slop intercept form is y = 2x - 7

Gina bought 2.5 pounds of peaches that cost $1.38 per pound at the grocery store. Amy went to the local farmer’s market and purchased 3.5 pounds of peaches at $0.98 per pound. Who spent more money, and how much more?

Answers

gina spent $3.45 in total. amy spent $3.43 in total. so gina spent more money and she spent 2 cents more

Answer:

Gina spent more money, she spent 2 more cents than Amy.

Step-by-step explanation:

Gina:     1.38x2=$2.76    1.38/2=69 cents

2.76+69= $3.45

Amy:     0.98x3=$2.94   0.98/2=49 cents

2.94+49= $3.43

Answer:

line B I hope this help!! good luckkk

Answer:line b

Step-by-step explanation:

In general, the slope intercept form assumes the formula: y = mx + b.

M is the slope  (lesson on slope)

Mnemonic : 'm' means 'move'

B is the y-intercept  (lesson on the y-intercept)

Mnemonic: 'b' means where the line begins.

B is where it intercepts so 1 intercepts the y axis and the only line that intercepts the y axis at 1 is line b
